HELP!!!!!!

Okay I'm new to the FE world so please bare with me. I picked up a supposed 390 last weekend, scrapped the dirt off it and we cant find any casting numbers. I found the block date "2L8" but no castings. the block has 352 all over it, and some other numbers right beside or above the 352's like 91,54and DIF.

We drained it and flipped it over and the bottom of the block has ribs on the sides leading down to the oil pan??? what does this mean?? took the oil pan off and the only numbers we found there were the ones off the crank "C4AE-B" what does this mean?

whats more confusing is that I did a stroke check on it and the stroke is 4 inches? I cant figure this out for anything, this damn motor is frustrating.

the next thing is, is that it has a 2brl carb on it. and one head that reads "D3TE-AA" and the other reads "C8AE-H" two different years?


can anyone please tell me just what the heck I have in my garage?

I greatly appreciate any information you can spare!!!

thanks,
John
